Abstract: 766,998. Aircraft trainers. COMMUNICATIONS PATENTS, Ltd. May 4, 1955 [May 26, 1954], No. 15617/54. Class 4. Apparatus for training a pilot in the landing of an aircraft with the aid of a three dimensioned array of indicators of known position with respect to the landing surface, comprises means representative of the array of indicators by means of which a projector establishes on a screen visible to the trainee, images representing the array, and means whereby the relative positions of the images on the screen are controlled in accordance with the assumed or computed relative positions of the aircraft and array. The embodiment described simulates landing on an aircraft carrier equipped with a row of lights, in the centre of which is a mirror reflecting a further light set in front of the mirror. The reflection of the further light appears in line with and in the centre of the row to an incoming pilot if he is on the correct angle of glide and heading. In Fig. 2, the casing 6 encloses a number of lights 8, and is formed with a horizontal row of holes 7 in one face. A perspex screen 10 has a bore 11 filled with epsom salts, and has a row of lights 12 mounted beneath it, so that on looking at the screen from the front, a single area of light is seen at 11, against the row of illuminated apertures 7, the light at 11 simulating the reflection of the further light in the mirror. The screen 10 is movable horizontally and vertically to displace the area 11 from its central position, if the trainee seated in a dummy cockpit moves the controls so as to depart from the correct glide path, Formulae are given for computing the displacement of area 11, in terms of simulated aircraft range, height, bearing from the aircraft carrier, &c. The apertures 7 and area 11 are projected onto a screen in front of the dummy cockpit, through a Dove prism 34 which can be rotated, so that the image on the screen rotates to appear to the trainee in the correct relation to the lateral axis of the cockpit. A formula is given for determining the rotation of the prism. A zoom lens unit 35 is also employed, and adjusted in accordance with the simulated aircraft range, to control the size of the images on the screen, and to simulate distance. The whole apparatus shown in Fig. 2 is mounted on top of a dummy cockpit so as to be rotatable about lateral and fore-and-aft axes, formulae being given for computing the angles of rotation in terms of aircraft position, orientation, &c. Coloured lights or audible signals in the cockpit may be controlled by the mechanism controlling the simulated indicated air speed indicator. In place of the movable area 11, light from a fixed lamp may be projected onto the screen by a movable mirror appropriately controlled. Specifications 751,628 and 753,365 are referred to.
